Only in extremely rare cases will a dhampir be born and grow to adulthood: generally the female does not come to full term and the baby is lost; in other instances, the mother comes to term and gives birth to a stillborn.
In some legends, a dhampir is not the direct offspring of a male undead and female mortal, but the seventh male descendant of any line of mortals with a male ancestor who became cursed with vampirism (this later legend depends upon the concept of vampires as blood-drinking high revenants).
Other legends claim that a dhampir could only be conceived by a male vampyr in the first night it rises as an undead, and again this is based on later legends rather than the original vampyr as a spirit creature."

Concentrating on the first and third paragraphs, I think a dhampir in Ravenloft is quite logical.
Victims of a victim's unfortunate circumstances, they can be THE ideal avatar of a tragic character. The Outcast Rating, due to the "health problems" (more so if the character's lineage is publicly known), would make for a great role playing challenge for any player of this game.
Thoughts?
Me? I've currently started writing a series of short stories based on such a version as what I just regurgitated. A bi-polar mortal dhampir transient that hunts vampires for a (very poor) living...
